My invention relates to an improved cable socket. It is generally known by those familiar with the art of drilling oil wells, and other deep wells, that it is frequently necessary to use tools of various kinds which are attached to a cable to be let down into the well being drilled, the same cable being used for the various tools at various times, and sockets of difierent kinds are required for diiferent tools. The means now used to attach a socket to the cable consists of providing a tubular member having stop means therein through which the cable can pass, but which acts as a stop for an enlarged end of the cable. The end of the cable is threaded through the stop means and the tubular member, and the end of the cable is then enlarged by well known means so the tubular member cannot be pulled therefrom means within the tube. Such tube is usually threaded to adapt it for attaching tools thereto. In this well known means of attaching a socket to the cable, it is necessary to cut the cable to remove the socket, inasmuch as such cables are usually of great length and are wound on a drum, or spool. Inasmuch as it is frequently necessary to change or replace sockets ongthe cable, loss of sections of the cable, the Babbitt metal or other material forming the enlarged end and the time necessary to again enlarge the end of the cable are lost.

The object of my invention is the production of a socket which is easily attached to, and easily removed from the cable, thus saving time and material in making such change.

l. accomplish hereinafter disclosed by means of the device hereinafter described, and illustratedon the accompanying drawing which'is hereby made a part of this specification, in which Hg. 1 shows the completed device with parts away to show the internal construction and the cable as it is attached to the socket.

Fig. 2 is a longitudinal sectional view of thedevice, not including the cap, adapted to show the contour of the chamber of the'device.

Fig. 3 is a sliding key, or plug for closing a slot as shown in Fig. 4, this figure belneaenlareed.

Fi 4 is a perspective view of the socket with this i cable installed, and without the cap.-

of the socket along broken lines .55 in F g. 4.

Referring to the drawing, I have shown cable a, which can be any ordinary wire or hemp cable or rope, having an end at enlarged. In the case of a wire cable the preferred enlargement'is made this object, and other objects 5 is'a cross sectional view or the portion 4 50 The inside chamber tion. A form is then placed around the v formation and the form is then filled with molten lead, or Babbitt metal, or other metal. This enlargement is preferably frusto-conical in shape. but 5 other forms of enlargement can be substituted and the principle of my invention can be adapted to such various forms. For a. hemp rope, a knot or other well known means for enlarging the end can be used.

The socket consists of a tube l, internally threaded at one end H so that selected tools can be screwed therein. Formed integral with tube 1 is an extension 8, which is likewise of tubular construction. The chamber in extension 3 can be described as in three parts. The inside diameter of portion ti, which is adjacent to tube l, is approximately the same diameter as said adjoining tube l. The center section ill is frusto-conical in shape, the larger diameter being adlacent to portion 8!, and the outside section it consists of a hole having an approximately uniform diameter of the smaller end of the frusto-conical hole in section 82. A slot 5d of approximately uniform width extending through the wall of extension 8, laterally through section as and a portion of section as is adapted for the cable to be passed therethrough into thechamber in extension s, and in the wall of portion 8i and section ill of said er:- tension slot at is enlarged, and identified on the as as, to adapt it to receive the enlarged 'end 9: of cable 9. By this construction it will be noted that the cable with the enlarged end is easily assembled with the cable socket.

The outside periphery of extension a has a threaded portion to between the ends thereof, and from said threaded portion to the outside and of said extension the shape is preferably frustoconical, and is identified as as.

' a sliding key ill is fitted within slot es, and 40 should be assembled with said extension a when the cable is therein. sliding key all. should have threads 86 at one end to coact with threaded portion at. This key is shown more in detail in Fig. 3. It is noted that it has a longitudinal flange as on each side thereof which coacts-with a runway MA when .the key is assembled with extension ii, to-assist'in holding the key in assembled relation with said extension.

A cap 5 shown in Fig.1 is tubular in shape. can be divided into three sections to correspond with the outside periphery of extension 8. The endsection 6!. should have an inside diameter approximately the same as !the outside diameter of the portion BIA of extenby spreading. or bending the wires in a v 1 lsion 8 adjacent to tube 1. The interspaced porsembled with extension I, and after it is assembled as herein described cap i can be screwed on to extension 8, thus holding the cable within the socket, and strengthening the extension of the socket,

when it is desired to remove thecable from the socket, cap 8 is unscrewed and removed, sliding key 01 is removed from slot, and the cable can be removed through slot 84 and its enlargement 85.

Having described my invention I claim:

1. A socket for a cable having an enlarged end consisting of a member adapted to have a tool attached thereto, an extension on said member having a chamber therein, said chamber being adapted to receive and hold the enlarged end of the cable and a short length of the cable adjacent to the enlarged end, an opening through the wall of the chamber adapted for the enlarged end of the cable and the short adjacent length of the cable to pass therethrough into the chamber, and a cap in shape and size adapted to approximately cbver the extension and further adapted to reiniorce the wall of the chamber, said cap being removably attached to said extension, and said cap having an opening in both ends thereoi adapted to thread the enlarged end 01' the cable therethrough,

2. A device described in claim 1 in which the opening through the wall of the chamber has a closure, the inside surface oi the closure being adapted to conform to the general contour oi the inside wall of the chamber and the outside surface of the closure being adapted to conform to the outside contour of the extension.

3. A socket for a cable having an enlarged end consisting of a member adapted to have a tool attached thereto, an extension integral with said member, said extension having a chamber therein adapted to receive and hold the enlarged end of the cable and a short length of the normal cable adjacent to the enlarged end, an ope ning through the wall of the chamber adapted for the enlarged end and adjacent short length of the cable to pass therethrough into the chamber, a closure for said opening having a longitudinal flange thereon, longitudinal runways in the walls of the opening into the chainher. said flanges and rlmways being adapted to cooperate and interlock the closure with the extension, the inside surface of the closure being shaped to conform with the inside wall of the chamber and the outside surface of the closure being adapted to conform with the outside surface of the extension when said closure is assembled with the extension, 9. cap in shape and size adapted to cover said extension when the closure is assembled therewith, said closure having an opening at both ends thereof of sufficient size to thread the enlarged end of the cable therethrough.

4. A device described in claim 3 in which a portion of the extension is threaded, and the interior of the cap is threaded, said threads being adapted to cooperate in attaching the cap to the extension.
